INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Replace O-rings of low-pressure flexible hose and high-pressure flexible hose with a new ones, andapply compressor oil when installing.
• When recharging refrigerant, check for leaks. Refer to MTC-92, "
Checking of Refrigerant Leaks".
Removal and Installation for Compressor Clutch - Type 1INFOID:0000000005716140
REMOVAL
1. Remove the compressor. Refer to MTC-79, "Removal and Installation of Compressor - HR16DE".
2. Remove the center bolt by holding the clutch disc steady using Tool.
3. Remove the clutch disc and shim(s). CAUTION:
Retain shim(s) for installation.
4. Remove the snap ring using external snap ring pliers.
5. Remove the pulley assembly using suitable tool (A). CAUTION:
To prevent deformation of th e pulley groove, the puller
claws should be ho oked under (not into) the pulley groove.
6. Remove the magnet coil snap ring (A) using a suitable tool. Then remove the magnet coil (1) from compressor shaft.Tool number : (J-44614)

5. Install the center bolt using Tool.• After tightening the center bolt to specification, check that the
pulley rotates smoothly.
INSPECTION OF CLUTCH DISC TO PULLEY CLEARANCE
1. Check the clearance around the entire periphery of the clutch
disc.
2. If specified clearance is not obtained, replace compressor clutch.
BREAK-IN OPERATION
When replacing compressor clutch assembly, always conduct the break-in operation. This is done by engag-
ing and disengaging the clutch about 30 times. Break-in operation raises the level of transmitted torque.
Removal and Installation for Compressor Clutch - Type 2INFOID:0000000005716141
REMOVAL
1. Remove the compressor. Refer to MTC-81, "Removal and Installation of Compressor - MR18DE".
2. Remove the three rubber plugs (1) from the clutch disc (2). To ease removal, apply some light lubricant to the three rubber
plugs (1).
NOTE:
The three rubber plug holes are used for attaching the suitable
tool when removing and installing the center bolt.
3. Remove the center bolt by holding the clutch disc steady using a suitable tool (A).
4. Remove the clutch disc and shim(s). Center bolt : 12 N·m (1.2 kg-m, 9 ft-lb).

1. Check the clearance around the entire periphery of the clutch disc (1) and pulley (2) using a suitable tool (A).
• Measure the clearance for the type 1 compressor as shown.
2. If specified clearance is not obt ained, replace compressor clutch.

ing and disengaging the clutch about 30 times. Break-in operation raises the level of transmitted torque.
Removal and Installation of Low-Pressure Flexible HoseINFOID:0000000005396523
REMOVAL
1. Use the recovery/recycling equipment to evacuate the refrigerant.
2. Remove engine cover (MR18DE only).
3. Remove cowl top cover. Refer to EI-22, "
Removal and Installation".
4. Remove lower dash insulator.
5. Remove ground wire harness (1).
6. Remove bolt (A) and nut (B) from low-pressure flexible hose (2) bracket.Clutch disc to pulley

6. Remove evaporator (1) with lower blower case (2) from A/C unitassembly.
7. Mark the position of the thermo control amp. if reusing the evap- orator and then remove thermo c ontrol amp. (3) from evaporator
(1), if equipped (MR18DE - TYPE 2 systems).
8. Remove evaporator (1) from lower blower case (2).
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Replace O-rings for A/C piping with new ones, and apply compressor oil when installing.
• If reusing the evaporator, install the thermo contro l amp. at the position marked when removing the
thermo control amp., if equipped (MR18DE - TYPE 2 systems).
• When recharging refrigerant, check for leaks.
Removal and Installation of Expansion ValveINFOID:0000000005396530
REMOVAL
1. Use the recovery/recycling equipment to evacuate the refrigerant.
2. Remove cowl top cover. Refer to EI-22, "
Removal and Installation".
3. Remove lower dash insulator.
4. Disconnect low-pressure flexible hose and high-pressure pipe from evaporator. Refer to MTC-59,
"Removal and Installation".
5. Remove expansion valve bolts (A), and then remove expansion valve (1).
CAUTION:
Cap or wrap the joint of the pi pe with suitable material such
as vinyl tape to avoid the entry of air.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Replace O-rings of evaporator with new ones, and apply compressor oil when installing.
• When recharging refrigerant, check for leaks.
Checking of Refrigerant LeaksINFOID:0000000005396531
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C oil leak-
age, damage and corrosion. A/C oil leakage may indicate an area of refrigerant leakage. Allow extra inspec-
tion time in these areas when using either an electronic refrigerant leak detector or fluorescent dye leak
detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 25 to 50 mm (1 to 2 in) per second and no further than 1/4 inch from the component.
